My car deffo feels better on super, but we are only talking a few bhp really.

When i fitted my induction kit the car lost top end power, but felt more torquey

I had an Evo that never did amazing numbers on the Dyno,

Cars that made 30- 40 bhp more than my car on the same dyno were slower out on the road ?

My 03 vts got a very reliable figure i feel. It serviced around every 3k,

green panel filter
421 mani
piper cat back
and a full service before run and it made 126.6bhp

any trackdays coming up? woud like to see what it can do with more power

Same... top end power seems to be lacking in my VTR, hits 100 comfortably, anything over it reeally seems to struggle
Yes i realise i probably hasnt got much more to give, but considering my mates 1.25 zetec S hit 110 with 4 of us, one would hope

30 - 70 is amazing though

Was lifted from an impreza with a 73mm to 62mm reducer pipe

would it not make more sense having the air feed coming from the other side instead of over the mani?

No room :/ 4" cold air feed, its now off though, it never actually touched the mani but kinda defeats the objective of having a 'cold air feed' when heat from the mani heats the pipe up, i dont normally drive it for very long though so it never gets that hot, with the car being stop start

AndySAXO^p · 22nd September 2010, 22:47

which cams should be around 135-145 dude... who mapping it? mapping on the standard ecu?

sexy_gt · 23rd September 2010, 18:55

brand new 708's andy sorting me with a predator. considering holding it a month to get some atpower bodies.

AndySAXO^p · 23rd September 2010, 19:08

yer sound good, who mapping it?

why would you think that pipe would supply cold air anyway -80% of surface area of filter is open to hot air from engine bay --
air will always come the easiest way it can ,so that cold air pipe is quite frankly pointless --sorry

For real ? Hot air = less power

What about just whacking an air filter straight onto the throttle body & Putting in a bonnet scoop above ?

thought a good cold air feed would of been better than none at all? not clue'd up on the whole induction kit side of things.

henryvtr · 23rd September 2010, 22:25

my mk 1 vtr with straight exhaust-decat-mani- induction-lightened standard fly and fast road clutch and home ported throttle body made 93.18 bhp at 5500rpm and 100.93 ft-lb torque at 2600rpm. dynod on dynojet dyno at janspeed and they will only give you wheel figures, he said flywheel is estimated by others. car goes very well. think must be around 115bhp at fly tho and was 90 before. car only done 50k so would expect to be healthy anyway

titchster · 24th September 2010, 07:22

93bhp @ the wheels roughly translates to 103/105bhp @ fly using 17% transmission loss.

my rr operator quoted 20% so at 17% i could be little more?

dont know if to be gutted at the low figure or be pleased with how well it does
